"The ancestry of the Ingleby line can be traced from a younger sibling of William 'I' d'Aubigny (the husband of Cecilia). Charter evidence indicates this was likely a brother, whose wife was previously married to NN de Chauveni (or Chauvigny): it is also possible given the occasional changes in toponyms that a sister of William had married, with her issue chosing either d'Aubigny or de Chauveni as a surname. Helias or Elias d'Aubigny was one son, whose brothers were Iwen d'Aubigny (also Iwen de Chauveni in some charters) and Geoffrey de Chauveni." [John P. Ravilious, citation details below]
